Secrets AI Free vs Premium: Is Upgrading Worth It?
The free tier answers one question: is the conversation quality worth paying for? It answers little else. With 20 messages per day, 200 non-refilling Moments, and a memory window of 2-3 exchanges, the free plan delivers a genuine preview of the chat engine but not a usable long-term experience. Whether upgrading is worth it depends on what you want to do with the platform.
This page runs the numbers across all five tiers — what each plan includes, what the real cost of media generation looks like in practice, and which plan fits which use pattern.
For the broader platform evaluation, see the full review.
What You Actually Get for Free
The Secrets AI free tier includes:
- 20 messages per day (500-character maximum per message)
- 200 starting Moments — one-time grant, never replenished
- Basic short-term memory: last 2-3 exchanges only
- No image generation access
- No video generation access
- No voice call access
- Full character library browsing and chat initiation
The free tier does one thing well: it lets you evaluate whether the conversational AI is worth paying for. You can engage with any pre-built character, test the AI's personality and responsiveness, and form an opinion on conversation quality — all without spending money.
What it cannot show you: media quality (no generation access), relationship continuity (memory resets constantly), or platform depth (20 messages covers less than a single genuine session for most users). The 200 starting Moments run out after roughly 4-8 images or 2 minutes of voice — whichever you try first.
Verdict: the free tier is a demo, not a product.

Is the Free Tier Enough?
For evaluating before buying: yes. For any sustained use: no.
Two hundred Moments cover roughly 4-8 static images if you spend them all on generation. A single long video clip costs 600 Moments — 3x the total free allocation. Voice calls at 100 Moments per minute exhaust the starting grant in 2 minutes. After the initial 200 Moments are spent, no media generation is possible on the free tier regardless of how long you stay on the plan.
The 20-message daily cap combined with the 2-3 exchange memory window means every conversation starts from a blank slate. There is no relationship continuity possible — the AI does not remember your name from yesterday, the dynamic you established last week, or anything beyond the last few messages in the current session. The AI companion simulation requires memory to function as advertised; without it, what you have is a general chatbot.
Which Paid Plan Delivers the Best Value?
Lite ($5.99/mo) — Entry Level with Real Limitations
Lite raises the daily message cap to 100 and provides 1,000 Moments per month. Memory extends to approximately 14 days of basic long-term recall — a meaningful improvement over the free tier's session-only memory.
The Moments constraint is tight: 1,000 Moments monthly covers approximately 20-40 images, or 20 short 3-second video clips, or 10 minutes of voice — not a comfortable mix of all three. Lite serves users who primarily want more conversation with occasional image viewing. It is not sufficient for regular media generation.
Plus ($9.99/mo) — The Recommended Starting Point
Plus removes the daily message cap entirely and delivers 3,000 Moments per month. Memory extends to roughly 30 days with topic and tone awareness — the AI begins tracking not just what you said but how you tend to feel and how conversations typically develop with your character.
Three thousand Moments allows approximately 60-120 images, 5 long video clips, or 30 minutes of voice per month — or a reasonable combination of all three for moderate users. Full image and video generation access opens up. The price-to-capability ratio is the best of any tier.
For most users, Plus is the correct entry point. It delivers the full platform experience within a workable Moments budget.
Premium ($19.99/mo) — The Complete Experience
Premium unlocks everything that makes Secrets AI's companion simulation work properly: unlimited memory recall, an emotional timeline that tracks relationship development across all sessions, Time Machine for revisiting past conversation states, 4x memory access multiplier, and a 60% context length boost per session.
The Moments jump to 8,000 per month with a 10% top-up bonus. Premium AI models produce noticeably stronger conversational output. This tier is designed for users who want the AI companion to function as a genuine long-term relationship simulation — remembering what you said three months ago, tracking how the relationship has evolved, and adjusting its behavior accordingly.
Ultimate ($39.99/mo) — Power User Territory
Ultimate adds 15,000 Moments monthly (with 15% top-up bonus), group chats with up to three simultaneous AI companions, persona switching, 6x memory access, and a 100% context length boost over baseline.
The group chat and persona features are Ultimate-exclusive. Whether they justify the $20 premium over Premium is a question of whether those specific features are part of your intended use. For most users, they are not — in which case Premium delivers better value at $39.99/month becoming unnecessary overhead.
The Memory Gap Is What Really Matters
The most consequential difference between free and any paid tier is not message limits or Moments — it is memory. The table above shows the progression, but the practical impact deserves emphasis.
On free: every conversation begins as if you have never spoken before. The AI has no record of prior sessions. Relationship simulation is impossible. The AI cannot reference the conversation you had yesterday, remember your preferences, or build on previous emotional exchanges.
On Plus ($9.99/month): 30-day topic and tone memory. The AI knows what you tend to talk about, how conversations usually develop, and maintains the emotional register of the relationship over a month. This is the baseline for what "AI companion" actually means.
On Premium ($19.99/month): unlimited memory with emotional timeline. The AI tracks the entire arc of the relationship — significant moments, evolving dynamics, established preferences, emotional history. Time Machine lets you revisit past conversation points.
The 200-Moments free tier cannot demonstrate any of this. The free tier's memory limitation is the single most important reason the free experience does not represent the paid product.
Real Cost of Media Generation
Premium tier (8,000 Moments/month) usage scenarios:
- Text-only heavy user: 1-2 Moments per message = effectively unlimited text
- Image-focused: approximately 160-320 images
- Video-focused: approximately 13 long clips (at 600 Moments each) or 160 short 3-second clips
- Mixed use (100 images + 5 long videos + 30 min voice): approximately 7,500 Moments used, leaving 500 in reserve
Plus tier (3,000 Moments/month) usage scenarios:
- Approximately 60-120 images
- Approximately 5 long video clips (at 600 Moments each) or 60 short clips
- Approximately 30 minutes of voice calls
- Mixed use (50 images + 2 long videos + 10 min voice): approximately 3,450 Moments — slightly over; budget carefully
Annual Savings Worth Considering
| Tier | Monthly Rate | Annual Rate | Annual Saving |
|---|---|---|---|
| Lite | $5.99 | $4.00 | $23.88/year |
| Plus | $9.99 | $6.67 | $39.84/year |
| Premium | $19.99 | $13.33 | $79.92/year |
| Ultimate | $39.99 | $26.67 | $159.84/year |
The 33% annual discount is consistent across all paid tiers. The practical recommendation: start monthly, run for two to three months to confirm usage patterns, then switch to annual if the platform is part of your regular routine. Do not commit to annual billing until you are confident in your use pattern.

FAQ
Yes, indefinitely. The free tier has no expiry. You can use 20 messages per day and access the character library forever without paying. The constraint is that the 200 starting Moments do not replenish — once spent, no media generation is available without upgrading or purchasing Moments separately.
Text chat continues normally — messages cost 1-2 Moments only from paid plans; the free tier's message limit is what applies, not Moments for text. Media generation (images, video, voice) becomes unavailable until you upgrade to a paid plan or purchase Moments. You cannot buy Moments as a standalone purchase on the free tier — you need an active subscription to buy top-up bundles.
You can cancel your paid subscription, after which your account reverts to free tier access at the end of the billing period. Downgrading does not delete your characters, chat history, or generated content — these remain in your account. However, memory access on the free tier reverts to 2-3 exchanges, meaning the AI will not actively recall Premium-era conversation history in future sessions.
For most casual users, Plus ($9.99/month) is sufficient. Unlimited messaging, 3,000 Moments, and 30-day memory recall covers the full platform experience at a workable cost. Premium ($19.99/month) is worth the upgrade specifically if you want the emotional timeline memory, Time Machine feature, or premium AI model access. For occasional use without heavy media generation, Plus is the correct choice.
